Improvement in current-wheels

IMPROVEMENT IN CURRENT-WHEELS.

The Schedule referred to in these`Letters Patent and making peutI of thesame I, EUGENE A. WHITE, of Boston, in the county of Suffolk, and Stateof Massachusetts, have invented a new and Improved Tide andCurrent-Wheel, of which the following is aspecication.

My invention relates to the arrangement and combination of oats, pins,frame-work, 85o., in such a manner that by thetloatso'ering resistanceupon one side of the wheel, and no resistance on the other side, theaction of the water causes the wheel to turn in the same direction,whichever way the current of the water may run.

The accompanying drawing represent my wheel in a sluice-wayy drepresenting the sides;

c, the bottom.

I will state however, that the more common way,

and probably more convenient way of building and securing my wheel,Wllbe b'y dispensing with a sluice-` way, and resting it upon some rockon the bottom, or upon some composition placed there for that purpose,and using pilesv instead of the sides d of the sluiceway represented.` rY a represents an upright shaft,"plaeed and revolving in the bottom c,and secured 'at thev top by means of the cross-bar b. l

k is a pinion or axle,ipassing through the bar b.

e f and g are floats, iu different positions.

s s are the arms, holding the floats.`

h h are connecting rods,'passing across from arm to another,strengthening'them. f r

p p are pins, which project upward from each arm s, excepting the topones. l

ODG

. In practical operatiomsupposing the current to be running in thedirection indicated by the arrow ,in the drawing, the current strikesthe floats e c, g g, and ff.4

The floats e e lay closely against the pins behind" them, resisting thepressure of the current.

The current in pushing them, pushes that side of the Wheelpartly-round.' At the same time the-floats f j' rise as high as theconnecting-rods h h will allow them to, and the water passes under them.The

floats g g, it will be noticed, are just commencing to rise.

When the iloats f f swing round to the place now `occupied by the lloatse e, they will assume the posi- 4tion of theoats e e, and help movethewheel.

ln some cases it may be necessary to place weights on the floats, inorder to makeV them drop readilyI at the right instant. l

By extending my floats, and making them wider, I

ner above described.
